I am in Canada so not sure if it applies. I did not get any testing for disability. Previously I had a psychiatrist who ordered neuropsychological tests which showed slower brain processing in my brain etc. When it was time for my back to work program, my union rep arranged a meeting at my employers head office with them, union rep, and disability insurance rep. I had a letter from my CFS Special interest doctor saying I was not fit for any return to work. His knowledge of not going beyond limits and testing would be going beyond limkts. He also did my CPP disability which I got first time.
